- Abstract: Integrated quantum photonics, i.e. the generation, manipulation and detection
of quantum states of light in integrated photonic chips, is revolutionizing the
field of quantum information in all applications, from communications to
computing. Although many different platforms are being currently developed,
from silicon photonics to lithium niobate photonic circuits, none of them has
shown the versatility of femtosecond laser micromachining (FLM) in producing
all the components of a complete quantum system, encompassing quantum sources,
reconfigurable state manipulation, quantum memories and detection. It is in
fact evident that FLM has been a key enabling tool in the first-time
demonstration of many quantum devices and functionalities. Although FLM cannot
achieve the same level of miniaturization of other platforms, it still has many
unique advantages for integrated quantum photonics. In particular, in the last
five years, FLM has greatly expanded its range of quantum applications with
several scientific breakthroughs achieved. For these reasons, we believe that a
review article on this topic is very timely and could further promote the
development of this field by convincing end-users of the great potentials of
this technological platform and by stimulating more research groups in FLM to
direct their efforts to the exciting field of quantum technologies.
